Banner BT23S Bifurcated Glass Fiber Cable

(Stendardo, Parte n.: 17276)

Tipo di prodotto: Bifurcated diffuse reflection glass fiber cable. Fiber only, fiber optic amplifier required for operation.

✅ Model Definition

BT: Bifurcated fiber (one transmit fiber + one receive fiber)

23: Serie, stainless steel flexible armor sheath, high-temperature glass fiber

S: Straight threaded sensing tip (BAT23S is the 90° elbow version)

📋 Core Specifications

🧰 Typical Applications

1. Part presence detection inside high-temperature equipment (forni, die casting, heat treatment stations)
2. Small-space, oil/cutting fluid environment for part counting and position detection
3. Installation locations subject to mechanical pulling and abrasion (stainless steel armor resists compression)
4. Metal machining, stampaggio ad iniezione, heat treatment production lines

⚠️ Important Notes

1. This is only fiber assembly, NOT a photoelectric sensor. An external fiber amplifier is mandatory.
2. Glass fiber cannot withstand sharp dead bends; bending radius less than 25 mm causes permanent fiber breakage.
3. 249 ℃ rating applies only to the sensing tip. The amplifier must not be placed in high-temperature zones.
4. Series comparison:

BT23S: Straight threaded tip, diffuse bifurcated fiber

BAT23S: 90° elbow tip, diffuse bifurcated fiber

IT23S: Thru-beam single fiber (separate transmitter and receiver assemblies)

🛠️ Troubleshooting

1. No signal: Inspect fiber end face for oil contamination or scratches; check if stainless hose crushed internal glass fibers; verify fiber connector cleanliness at amplifier.
2. Sfarfallio del segnale: Detection distance exceeds valid diffuse range; low reflectivity of target object; ambient strong light interference.
3. Increased light attenuation: Excessively small bend radius causing microcracks inside glass fiber bundle.

📌 Alternative Selections

OEM alternative from Banner: BAT23S (elbow version); BT23PMSS (PVC sheath low-temperature variant)

Alternativa domestica: High-temperature stainless steel armored bifurcated glass fiber, 5/16-24 filo, 0.9lunghezza m, compatibile con amplificatori in fibra.

Detection Distance for BT23S (Banner Bifurcated Diffuse Glass Fiber)

Importante: BT23S is just a fiber probe with no fixed detection range. Sensing distance depends entirely on the paired fiber amplifier.

✅ Typical Official Data (High-reflectivity white target)

1. Paired with Q45F amplifier: Massimo. 100 mm (4 pollice)
2. Paired with QS18F amplifier: ca. 37.5 mm (1.5 pollice)
3. Paired with classic D10 / D11 / D12 amplifiers: Typical stable range 20～60 mm

Nota: Target reflectivity greatly affects working range:

Bright white metal / white paper: close to maximum values listed above

Matte black workpiece: effective distance reduces by half or more

Oxidized surface of hot workpiece reduces reflectivity and shortens detection range

📌 Engineering Recommendation

Recommended stable operating range: 5～40 mm (stable performance for most working conditions)

Above 50 mm, signal margin decreases. Oil dust and workpiece color variation easily trigger unstable readings.

Diffuse fiber is short-range sensing, not suitable for long-distance detection.

Material Breakdown for Banner BT23S (Official Datasheet)

Note supplementari

1. Temperature rating determined by glass fiber and stainless steel sheath: Max tip temperature 249℃. Y-shaped plastic connector must be kept away from high-temperature zones.
2. Stainless steel hose resists cutting fluid, oil and mechanical pulling, ideal for machine tools and heat treatment environments.
3. Distinguish from plastic fiber versions with PVC sheath (max temp only 105℃). BT23S is glass armored fiber.

Banner BT23S Fiber Probe Installation Manual (Versione ingegneristica, Part No.17276)

Prodotto: Bifurcated diffuse glass fiber BT23S (fiber only, Banner fiber amplifier required. Amplifier powered separately)

Applicazione: Object presence detection in high-temperature & confined space, diffuse sensing

1. Panoramica del prodotto

BT23S is an inline straight bifurcated glass fiber. The Y-end splits into two fibers to plug into fiber amplifier. The opposite end is brass 5/16-24 UNC threaded sensing tip, protected by stainless steel armor hose.

Lunghezza totale: 36 In (0.914 M)

Max Tip Temperature: 249 ℃

Minimum Bend Radius: 25 mm

Sensing Mode: Diffondere

2. Ispezione pre-installazione
3. Visual check upon unpacking: Stainless hose no crushing or twisting; fiber end face no scratches or oil; Y-connector no cracking.
4. Prohibited operations: Bending radius less than 25 mm, treading, heavy pulling on armor hose, glass filaments break easily.
5. Confirm matched amplifier model (D10/D11/D12/Q45F/QS18F etc.). Amplifier cannot be placed in hot area.
6. Prepare mounting hardware: 5/16-24 UNC lock nut and mounting bracket.
7. Procedure di installazione meccanica

Fare un passo 1: Mount Sensing Tip

1. Machine 5/16-24 UNC threaded hole on equipment frame, or use lock nut + staffa di montaggio.
2. Screw BT23S brass sensing tip into threaded hole. Coppia di serraggio: 0.7~1.0 N·m. Do not over-tighten to avoid cracking fiber end face.
3. Adjust gap between probe face and workpiece: recommended stable working range 5~40 mm. Keep probe perpendicular to target surface.

Nota: Workpiece tilt reduces return light signal; tilt angle ≤10°.

Fare un passo 2: Route Stainless Steel Armor Hose

1. Maintain bending radius ≥25 mm throughout routing. Avoid dead bends and sharp edges cutting metal sheath.
2. Only brass sensing tip section can be placed in high-temperature zone. Stainless hose and Y-split connector must be located in area below 80℃.
3. Secure armor hose with cable clips to prevent repeated pulling from machine reciprocating motion.
4. Avoid continuous cutting fluid splash; oil buildup on end face attenuates optical signal.

Fare un passo 3: Insert Fibers into Amplifier

1. Clean fiber ferrule end face: Wipe two fiber tips with lint-free paper dipped in anhydrous ethanol and dry thoroughly.
2. Insert transmit (Tx) and receive (Rx) fibers into corresponding Tx / Rx ports on Banner amplifier, seat fully and fasten compression nut.

⚠️ Do not force insertion. Dirty fiber end face is the top cause of unstable signal.

4. Amplifier Setup (BT23S contains no circuitry; all adjustments on amplifier)
5. Power on amplifier (CC 10 ~ 30 V, refer to amplifier manual).
6. Teach-in calibration (2-point teach recommended)

Fare un passo 1: Teach background with no workpiece present.

Fare un passo 2: Teach target with workpiece in position.

3. Observe amplifier signal strength LED, ensure sufficient signal margin.
4. Save threshold, perform repeated workpiece in/out tests to eliminate missed detection and false triggering.
5. Divieti di installazione
6. ❌ Y-type plastic connector cannot be exposed to high temperature (max ambient temp ≤80℃). Only sensing tip rated for 249℃.
7. ❌ Fiber bend radius ＜25 mm causes permanent breakage of internal glass filaments and fiber failure.
8. ❌ Impact or scratch fiber end face; damaged end face leads to severe optical attenuation.
9. ❌ Install amplifier in high temperature or heavy oil environment.
10. ❌ Multiple fiber probes mounted closely together, optical crosstalk may occur.
11. ❌ Workpiece distance exceeds maximum sensing range of matched amplifier.
12. Manutenzione ordinaria
13. Periodically clean fiber sensing end face: lint-free paper + anhydrous alcohol to remove dust, oil and oxide scale.
14. Inspect stainless hose for crushing and cracks. Recheck fastening quarterly for vibrating equipment.
15. Periodically clean fiber connectors at amplifier side.
